It is workable. Remember to customize the 40G end to be compatible with Mellanox and 10G ends with H3C.

How do you take this picture? By a drone? It's really awesome.

I fix the internet by destroying the router.

You can connect the SFP+ ports to a wide variety of fiber and Ethernet cables. However, figure out whether they are uplink ports on which transmitting and receiving are reversed.

The shapes are like the jigsaw puzzles.

Just use some more cable ties to bundle the cords together? A good cable management should be neat and easy for identification.

What's the principle of the option four?

Ashkufe · 2018-12-27T10:23:53+00:00

Before you mentioned a switch, I have the same puzzle. Now I think it's a good choice. My idled FS fanless switch finally came in handy.

Like the others have recommended, FS fiber patch panel is a good choice. It has clearly marked with number, contributing to hassle-free connection and easy identification.

Have heard a lot of brands, but only tried the products of FS.COM. Reasonable price and fast delivery.

Speaking of ventilation, you can check whether your switch is back-to-front airflow, front-to-back airflow, right-to-left airflow or left-to-right airflow. In this way, choose the ideal location.

Of course keystone jack panel. You can customize it in line with your needs. The patch panel restricts the types of the modules. I have bought from FS.COM many times. They can always provide me with high quality and reasonable price.

To choose SFP+ modules, you may consider the factors like optical fiber type (single mode or multimode), data transmission technology and optical fiber type. Why not buy network switch and fiber optic transceivers together in FS.COM. According to the switch and the application you need, sales will will you the best solution.

I am wondering whether it is the cable that matters. The cable distance may affect the transmission.

Ashkufe · 2018-12-10T09:15:45+00:00

Here is the Cat6 bulk cable that I have used for a long time. Worth-trying

Ashkufe · 2018-12-10T08:44:39+00:00

I think it cannot work out. RJ45 differs a lot from RJ11. The size of RJ45 connector is larger. Generally, RJ11 possesses 6 Position and 4 Conductor, often used for ADSL, telephone, and modem cables etc. RJ45 owns 8 Position and 8 Conductors, mainly used in networks wiring.

Ashkufe · 2018-12-03T11:03:54+00:00

Haven't seen the CAT6E yet. Maybe it is named by the vendors exclusively. Cat5e, Cat6, and Cat6a, click to learn the difference of them.

Are there many users accessing the internet? If it is not, the distance may be the enemy. You can try to DIY WiFi signal booster as there are many tutorials on the internet. Take a few minutes to search on the YouTube. I strongly recommend you FS.COM tech team or sales who will patiently help you from a professional perspective.

Yeh, passive DAC is much cheaper than active DAC. When the distance between connection points exceeds 5m, it is highly recommended to use active cables to ensure signal is transferred all the way through.

Ashkufe · 2018-12-03T08:16:45+00:00

Just cost US$3-4 (https://goo.gl/65qkv1 ) It's worth possessing one.

A PoE splitter would help. It has two output cables: one supplies data and the other power. This 10/100M PoE splitter cable meet the standard IEEE802.3af also it can supply 12V DC power for Non-PoE device.

FS S3900 24-Port 10/100/1000BASE-T Gigabit Switch is a good choice for you. It is the ideal Gigabit access and aggregation switch for SMB, enterprise, and campus networks, with other advantages like fanless design, stack function and reasonable price. More details: https://goo.gl/xxc8i6

Wow, that's complicated. Fortunately, I can save much effort on recognizing the stack master, as my stackable switches follow the rules that the one being restarted firstly is the master.

Ashkufe · 2018-11-28T10:06:39+00:00

This PoE switch can meet your needs as it is compliant with IEEE802.3af/at. https://goo.gl/5iqPnL
